The Impact

Objectives This study investigates the hypothesis that hearing aid amplification reduces effort within conversation for both hearing aid wearers and their communication partners. Levels of effort, in the form of speech production modifications, required to maintain successful spoken communication in a range of acoustic environments are compared to earlier reported results measured in unaided conversation conditions. Design Fifteen young adult normal-hearing participants and 15 older adult hearing-impaired participants were tested in pairs. Each pair consisted of one young normal-hearing participant and one older hearing-impaired participant. Hearing-impaired participants received directional hearing aid amplification, according to their audiogram, via a master hearing aid with gain provided according to the NAL-NL2 fitting formula. Pairs of participants were required to take part in naturalistic conversations through the use of a referential communication task. Each pair took part in five conversations, each of 5-min duration. During each conversation, participants were exposed to one of five different realistic acoustic environments presented through highly open headphones. The ordering of acoustic environments across experimental blocks was pseudorandomized. Resulting recordings of conversational speech were analyzed to determine the magnitude of speech modifications, in terms of vocal level and spectrum, produced by normal-hearing talkers as a function of both acoustic environment and the degree of high-frequency average hearing impairment of their conversation partner. Results The magnitude of spectral modifications of speech produced by normal-hearing talkers during conversations with aided hearing-impaired interlocutors was smaller than the speech modifications observed during conversations between the same pairs of participants in the absence of hearing aid amplification. Conclusions The provision of hearing aid amplification reduces the effort required to maintain communication in adverse conditions. This reduction in effort provides benefit to hearing-impaired individuals and also to the conversation partners of hearing-impaired individuals. By considering the impact of amplification on both sides of dyadic conversations, this approach contributes to an increased understanding of the likely impact of hearing impairment on everyday communication.

CONTEXT AND OBJECTIVE: Nouns and verbs indicate actions in oral communication. However, hearing impairment can compromise the acquisition of oral language to such an extent that appropriate use of these can be challenging. The objective of this study was to compare the use of nouns and verbs in the oral narrative of hearing-impaired and hearing children. DESIGN AND SETTING: Analytical cross-sectional study at the Department of Speech-Language and Hearing Sciences, Universidade Federal de São Paulo. METHODS: Twenty-one children with moderate to profound bilateral neurosensory hearing impairment and twenty-one with normal hearing (controls) were matched according to sex, school year and school type. A board showing pictures was presented to each child, to elicit a narrative and measure their performance in producing nouns and verbs. RESULTS: Twenty-two (52.4%) of the subjects were males. The mean age was 8 years (standard deviation, SD = 1.5). Comparing averages between the groups of boys and girls, we did not find any significant difference in their use of nouns, but among verbs, there was a significant difference regarding use of the imperative (P = 0.041): more frequent among boys (mean = 2.91). There was no significant difference in the use of nouns and verbs between deaf children and hearers, in relation to school type. Regarding use of the indicative, there was a nearly significant trend (P = 0.058). CONCLUSION: Among oralized hearing-impaired children who underwent speech therapy, their performance regarding verbs and noun use was similar to that of their hearing counterparts.

Abstract This article presents results of investigations of the angle of directional hearing acuity (ADHA) as a measure of the spatial hearing ability with a special emphasis on people with hearing impairments. A modified method proposed by Zakrzewski has been used - ADHA values have been determined for 8 azimuths in the horizontal plane at the height of the listeners' head. The two-alternative-forced-choice method (2AFC), based on a new system of listeners' responses (left - right instead of no difference - difference in location of sound sources) was the procedure used in the experiment. Investigations were carried out for two groups of subjects: normal hearing people (9 persons) and hearing impaired people (sensorineural hearing loss and tinnitus - 9 persons). In the experiment different acoustic signals were used: sinusoidal signals (pure tones), 1/3 octave noise, amplitude modulated 1/3 octave noise, CCITT speech and traffic noises and signals corresponding to personal character of tinnitus for individual subjects. The results obtained in the investigations showed, in general, a better localization of the sound source for noise type signals than those for tonal signals. Inessential differences exist in ADHA values for particular signals between the two groups of subjects. On the other hand, significant differences for tinnitus signals and traffic noise signals were stated. A new system of listeners' responses was used and appeared efficient (less dispersion of results compared to the standard system).

Positive Results

The deaf have a very fundamental problem, which is the ability to communicate and interact, so that it makes their very complicated. In the process of learning in basic education, the problem root faced by children with hearing impairment is the limitation in identifying and producing words. The learning process is limited to only rely on time at the school was an obstacle for them. Therefore, A-TooLips built as learning applications on mobile devices for the deaf children focusing on the ability to produce words. A-TooLips gives more time and places for hearing impaired children to learn, so that it helps their problem in communicating and interacting with others. It is explained in this paper that the A-TooLips has been successfully implemented and tested by some children with hearing impairment, and reached positive results.

Effect Of Age

The effect of age on accuracy of prediction of hearing impairment with the bivariate-plotting procedure was investigated in 72 normal-hearing subjects aged 20–69 years and in 86 sensorineural hearing-impaired subjects aged 20–83 years. The predictive accuracy with the bivariate-plotting procedure improved markedly when the data from subjects over 44 years of age were excluded from the bivariate plot. The predictive accuracy improved further when the construction of the line segments in the traditional bivariate plot was modified.

IntroductionOnly few international studies have focused on mental diseases among the hearing-impaired population. However, Fellinger et al. (2012) underline the high discrepancy between the current and future demand of mental treatment and the simultaneous impeded access to health care.AimsThe aim of this multicenter project is to conduct the first analysis of mental diseases among the hearing-impaired population in Germany in order to quantify and qualify the specific demands of treatment.ObjectivesIn order to achieve this aim, we compiled an extensive questionnaire battery.MethodsThis questionnaire battery measured sociodemographic data, non-verbal intelligence, quality of life, perception and suffering from stress, psychosomatic symptoms as well as personality traits.ResultsOur three samples consisted of 21 hearing-impaired patients with a history of mental diseases (EG-HI), 21 hearing-impaired subjects without mental diseases (CG-HI) and 21 hearing participants without any psychological disease (CG-H). Compared to the two control groups, the EG-HI shows significantly higher rates in different fields, i.e. participants perceive a lower quality of life, suffer from more psychosomatic symptoms and show more pronounced personality traits. The two control groups did not differ significantly from each other.ConclusionsCertain psychological characteristics among hearing-impaired patients can be detected which need to be accounted for in treatment. Furthermore, a hearing impairment is not inevitably linked to a reduced quality of life or even mental disorders. Therefore, future research should focus on risk factors and protective factors which could prevent mental diseases among the hearing-impaired population.Disclosure of interestThe authors have not supplied their declaration of competing interest.

A comparison was made of the self-esteem of 45 moderately-severe hearing impaired and 300 normal-hearing secondary school students in Hong Kong. Analysis indicated that the hearing impaired group, particularly the males, tended to report higher self-esteem in a number of dimensions of the self. The results provide no evidence that integration into the normal classroom has damaged the self-esteem of the hearing-impaired.

Ten normally hearing and 10 age-matched subjects with moderate-to-severe hearing impairment were recorded producing a protocol of 18 basic syllables [/pi/,/pa/,/pu/; /bi/,/ba/,/bu/; /ti/,/ta/,/tu/; /di/,/da/,/du/; /ki/,/ka/,/ku/; /gi/,/ga/,/gu/] repeated five times. The resulting 90 syllables were digitized and measured for (a) total duration; (b) voice-onset time (VOT) of the initial consonant; (c) fundamental frequency (F 0 ) at midpoint of vowel; and (d) formant frequencies (F 1 , F 2 , F 3 ), also measured at midpoint of vowel. Statistical comparisons were conducted on (a) average values for each syllable, and (b) standard deviations. Although there were numerical differences between normally hearing and hearing-impaired groups, few differences were statistically significant.
